| Abstract | In Thailand, most of primary commercial energy derived from imports; therefore, Thailand need more energy security. This study focus on electricity generation using biogas from anaerobic co-digestion of Napier grass and poultry manures in Thailand because the climate of Thailand is appropriate for using biogas technology. Moreover, according to the Alternative Energy development Plan (AEDP) 2012-2021, prepared by Department of Alternative Energy Development and Efficiency (DEDE), electricity generation from biogas from Napier grass is 3000 MW by 2021. The potential of biogas production can increase by multiple biodegradable substrates (Co-digestion). Poultry manure is one of the most encouraging feedstocks which can be mixed with Napier Pakchong1 grass for co-digestion. The potential of electricity generation using biogas from co-digestion of Napier grass and poultry manures is approximately 1,604 MW or 2.46kW/ Rai of cultivated area. Nakhon Ratchasima is a province which has highest potential. This study identified a suitable technology and estimated appropriate size of digester and generators for electricity generation using Napier Pakchong1 grass and poultry manures in Thailand based on technical and financial analysis. Using UASB digester with 1966 kW generator is the most attractive project in term of financial benefits that can yield Net Present Value (NPV) 117.9 million THB with Internal rate of return (IRR) 43.1% and payback period 4.61 years; however, it is also the most sensitive in cost changing and quantity of feed stock. Moreover, UASB digester require professionals to control the system therefore CSTR can also used for biogas production instead of UASB. |
